1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
A. TROPICAL CYCLONE SUMMARY:
(1) AT 291800Z, TROPICAL CYCLONE 03B (THREE) WAS LOCATED NEAR
6.6N 78.8E, APPROXIMATELY 904 NM NORTH- NORTHEAST OF DIEGO GARCIA,
AND HAD TRACKED WEST-NORTHWESTWARD AT 08 KNOTS OVER THE PAST SIX
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS
GUSTING TO 45 KNOTS. SEE REF A (WTIO31 PGTW 292100) FOR FURTHER
DETAILS.
(2) NO OTHER TROPICAL CYCLONES.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION (INVEST 91B) PREVIOUSLY LOCATED
NEAR 6.4N 79.6E, IS NOW THE SUBJECT OF A TROPICAL CYCLONE WARNING.
SEE PARA. 1.A.(1) FOR FURTHER DETAILS.
(2) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED
NEAR 4.8N 104.0E, IS NOW LOCATED NEAR 6.7N 100.3E, APPROXIMATELY 388
NM NORTHWEST OF SINGAPORE. ANIMATED ENHANCED INFRARED IMAGERY SHOWS
PERSISTENT DEEP CONVECTION OBSCURING A CONSOLIDATING LOW LEVEL
CIRCULATION. 93W IS BENEFITTING FROM WESTWARD AND POLEWARD OUTFLOW
WITH MODERATE TO HIGH (20-25 KNOT) VERTICAL WIND SHEAR (VWS) THAT IS
EXPECTED TO DECREASE IN THE FUTURE. SEA SURFACE TEMPERATURES ARE
WARM (28-29 CELSIUS) AND WILL SUPPORT FURTHER DEVELOPMENT. GLOBAL
DYNAMIC MODEL GUIDANCE IS IN GOOD AGREEMENT, PREDICTING DEVELOPMENT
ONCE 93W REACHES THE WARM WATERS OF THE ANDAMAN SEA ON ITS WESTWARD
TRACK ACROSS THE BAY OF BENGAL. THE POSSIBILITY EXISTS FOR
DEVELOPMENT TO BE DELAYED SHOULD 93W TRACK OVER SUMATRA. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO MEDIUM.
(2) NO OTHER SUSPECT AREAS.
2. SOUTH INDIAN OCEAN AREA (135E WEST TO COAST OF AFRICA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION (INVEST 96S) PREVIOUSLY LOCATED
NEAR 8.9S 102.9E, IS NOW LOCATED NEAR 8.9S 103.4E, APPROXIMATELY 280
NM WEST-SOUTHWEST OF JAKARTA, INDONESIA. ANIMATED ENHANCED INFRARED
IMAGERY AND A 291144Z 91GHZ SSMIS MICROWAVE IMAGE DEPICTS DEEP
CONVECTION CURVING IN FROM THE SOUTHWEST OF A LOW LEVEL CIRCULATION
CENTER (LLCC). A 291408Z SCATSAT-1 OSCAT IMAGE REVEALS A BROAD
REGION OF 30 KNOT WINDS IN THE WESTERN AND NORTHERN QUADRANTS. 96S
IS UNDER A REGION OF HIGH (25-30 KNOT) VERTICAL WIND SHEAR, WITH A
NARROW REGION OF LOWER SHEAR VALUES TO THE SOUTHEAST. SEA SURFACE
TEMPERATURES WILL REMAIN WARM (28-29 CELSIUS) IN THE REGION SOUTH OF
JAVA. GLOBAL DYNAMIC MODELS AGREE THAT 96S WILL CONTINUE DEVELOPING
AS IT TRACKS EASTWARD TO THE SOUTH JAVA, INTERACTING WITH THE
REMNANTS OF 95S BEFORE A LATE TAU TURN TOWARDS AUSTRALIA. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 28 TO 33 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS REMAINS HIGH. SEE REF B (WTXS22 PGTW 290430) FOR FURTHER
DETAILS.
(2) THE AREA OF CONVECTION (INVEST 95S) PREVIOUSLY LOCATED
NEAR 11S 110.8E HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
(3) NO OTHER SUSPECT AREAS.//
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 1.B.(1) TO
WARNING STATUS. AREA IN PARA 1.B.(2) TRANSFERRED FROM THE ABPW
BULLETIN AND UPGRADED TO MEDIUM.//

Depression over Southeast Bay of Bengal:
Latest observations and satellite imageries indicate that the well marked low pressure
area over southeast Bay of Bengal & neighbourhood concentrated into a Depression and
lay centred at 0830 hrs IST of today, the 06 December, 2017 near Latitude 8.5? N and
Longitude 88.5 ?E, about 1160 km to the southeast of Machillipatnam and 1250 km southsoutheast
of Gopalpur. The system is very likely to move northwestwards and reach Andhra
Pradesh coast around 8th December evening. The system is likely to intensify further into a
deep depression during next 48 hours. However, there is a probability of slight weakening of
the system when it reaches near Andhra Pradesh coast.
